Diethyl 2-amino-5-[(E)-(1-methyl-1H-pyrrol-2-yl)methylideneamino]thiophene-3,4-dicarboxylate

Abstract

The structure of the title compound, C16H19N3O4S, shows the planes described by the thiophene and the pyrroles are twisted by 17.06 (4)°. Additionally, the structure shows the azomethine bond adopts the E configuration, while the pyrrole is disordered as a heterocycle flip [occupancy ratio 0.729 (5):0.271 (5)]. The three-dimensional network is well packed and involves N–H...O hydrogen bonding and π–π stacking [centroid–centroid distance = 4.294 (8) Å].
